Oh, yes... I haven't even had my first BAR launch and I roped myself into building an Estes V2 (24mm D/E power) for my brother-in-law. He was enthused about the rockets I was building so I thought he'd like the kit - we were at the store, he loved the kit, but it turns out he kinda expected me to do the building. No problem, really, I like to build. But just a couple of quickies - I went back a few pages and couldn't find any recent threads.
1. This plastic Estes is using... it feels like polypropylene, which virtually nothing sticks to. Does anybody know what it is? Directions mention CA for the rear centering ring, does anybody have any experience with this, or any suggestions for anything better?
2. How do you fill the mold seams on these pieces? Many coats of sandable primer? I figure if I can't hide'em I can probably run a paint line along them, but still...
3. I've thought of a minor deviation from the instructions, that is, instead of gluing the whole engine mount/read tailcone/centering rings in at one shot, put the CA around the rear centering ring, push the assembly into the main body tube to set the distance, attach/space the fins, then (after plenty of glue drying time, pull the tailcone/fins.engine mount back out, thoroughly fillet the fins inside and out, then with that assembly bascially rock solid, proceed with the gluing of the whole tailcone/fins/engine mount to the main body tube. I figured to do that in 2 stages as well, get the front ring glue in place, insert front ring part way, place glue for rear centering ring, and for tailcone/body tube joint, and finish sliding it togther (hoping I haven't forgotten the shock cord!)
4. Last one: This big boy has a 3/16" launch lug! Any problems replacing it with a 1/8" lug or just flying it off a 1/8" rod anyway? Is 36" long enough?
Thanks all, I hope I'm not retreading too much old ground...
